LinkedInDrip irrigation in alfalfa cuts water use, but isn't for everybody
The drought is forcing farmers to reexamine the way they water their crops, but converting to drip irrigation in alfalfa is unlikely to be widely implemented, reported David Wagner on KPBS Radio News.
The drip irrigation system conserves water - almost by half, said farmer Jack Cato - but is expensive and requires regular maintenance. After six years, the drip system is yet to pay for itself.
"Drip irrigation is not the answer for everything," said Khaled Bali, irrigation advisor with UC Agriculture and Natural Resources (UC ANR). "I would not recommend switching every acre in the Imperial Valley to drip irrigation."
Cato added that new drip irrigation users face a steep learning curve.
"Whatever farm starts doing this, he needs to take baby steps," Cato said. "It's not something you learn overnight, or in a book. You have to study your fields daily."
